Yii2 Rest api call multiple methods

Question

I am using this piece of code, and try using REST API in yii2. I tried to use two function as you seen in the code snippet.

1. getAllData

2. getSpecificData

    <?php namespace app\\api\\modules\\widgetmodule\\controllers; use yii\\rest\\Controller; class WidgetController extends Controller { public $modelClass = 'app\\models\\DynamicWidget'; public function actions() { return [ 'index' => [ 'class' => 'yii\\rest\\IndexAction', 'modelClass' => $this->modelClass, 'prepareDataProvider' => [$this, 'getAllData'] ], 'view' => [ 'class' => 'yii\\rest\\ViewAction', 'modelClass' => $this->modelClass, 'prepareDataProvider' => [$this, 'getSpecificData'] ], ]; } public function getAllData() { die('get all data'); } public function getSpecificData() { die('get specific data'); } } 

I tried two URLs for the two different methods,

http://localhost/api/web/widgetmodule/widget/getAllData

http://localhost/api/web/widgetmodule/widget/getSpecificData

But the output will always be like.

Quote get all data

Here is my URL manager code in api.php

'urlManager' => [
            'enablePrettyUrl' => true,
            'enableStrictParsing' => true,
            'showScriptName' => false,
            'rules' => [
                '<controller:\w+>/<action:\w+>/<id:\w+>' => '<controller>/<action>',
                '<controller:\w+>/<action:\w+>' => '<controller>/<action>',
                [
                    'class' => 'yii\rest\UrlRule',
                    'controller' => ['widgetmodule/widget']
                ]
            ],
        ], 
        'db' => $db,
    ],
    'modules' => [
        'widgetmodule' => [
           'class' => 'app\api\modules\widgetmodule\Module',
        ],

So could anyone help me, how to get different outputs with two different methods.

It is anyways calling the first method.

Any help will be appreciated.

Thanks in advance.

Answer 1

1- The only 2 actions you did define inside your controller are index and view and because index is rendering getAllData it is why you are getting that output.

2- the view action has no prepareDataProvider attribute.

maybe you meant something like this instead:

public function actions()
{
    return [
        'index' => [
            'class' => 'yii\rest\IndexAction',
            'modelClass' => $this->modelClass,
            'prepareDataProvider' => [$this, 'getAllData']
        ],
        'view' => [
            'class' => 'yii\rest\ViewAction',
            'modelClass' => $this->modelClass,
        ],
    ];
}

public function getAllData()
{
    // return some dataProvider instance to be used by index
    $modelClass = $this->modelClass;

    return new ActiveDataProvider([
        'query' => $modelClass::find(),
    ]);
}

And that is defining two actions: index and view where index's dataProvider is overriden by a custom function getAllData() . that requires something similar to those configs:

[
    'class' => 'yii\rest\UrlRule', 
    'controller' => ['widgetmodule/widget'], 
    'patterns' => [
        'GET,HEAD index'  => 'index',
        'GET,HEAD view/{id}' => 'view',
    ]
],

So you can access them within the following endpoints:

http://localhost/api/web/widgetmodule/widget/index
http://localhost/api/web/widgetmodule/widget/view/4

Now if your question is how to add an extra action to that in order to respond to the uri http://localhost/api/web/widgetmodule/widget/getSpecificData then you'll need to add this to your patterns:

'patterns' => [
    ...
    ...
    'GET getSpecificData'  => 'some-specific-data',
]

and define that action inside your controller as described in official docs by simply adding this:

public function actionSomeSpecificData()
{
    return 'some specific data';
}

Answer 2

First unset default index and view actions, like this:

public function actions()
{
    $actions = parent::actions();
    // unset default index action for custom our own code
    unset($actions['index']);
    unset($actions['view']);

    return ArrayHelper::merge($actions, [
        'index' => [
            'class' => 'yii\rest\IndexAction',
            'modelClass' => $this->modelClass,
            'prepareDataProvider' => [$this, 'getAllData']
        ],
        'view' => [
            'class' => 'yii\rest\ViewAction',
            'modelClass' => $this->modelClass,
            'prepareDataProvider' => [$this, 'getSpecificData']
        ],
    ];
}

Config routes like this:

[
  'class' => 'yii\rest\UrlRule', 
  'controller' => ['widgetmodule/widget'], 
  'patterns' => [
    'GET,HEAD index'  => 'index',
    'GET,HEAD view/{id}' => 'view',
 ]
],

Then you can call these urls:

http://localhost/api/web/widgetmodule/widget/index
http://localhost/api/web/widgetmodule/widget/view/4
